These are stress ratings only and operation at these conditions for extended periods may affect device reliability. This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used when handling this product. Damage can occur when exposed to extremely high static electrical charge. Telephone 610.992.0727 Page 2 of 7 Facsimile 610.992.0734 This datasheet contains PROPRIETARY information.

RE46C116 DC to DC Converter, Voltage Regulator and Piezoelectric Horn Driver Preliminary Product Specification R&E International Electrical Table Notes: 1/ The brown-out threshold voltage is the VO voltage at which the regulator and horn will be disabled. At VO voltages below the brown-out threshold Regout will be pulled to Vss. 2/ In normal operation, the regulator will provide high-side current of up to 20mA, but current sinking capability is typically under 1uA. The overvoltage clamp is intended to limit the voltage at Regout when it is pulled up by an external source. 3/ The limits shown are 100% tested at 25C only. Test limits are guard-banded based on temperature characterization to guarantee compliance at temperature extremes.
